[][src]Struct sgx_tstd::io::Error

pub struct Error { /* fields omitted */ }

The error type for I/O operations of the [Read], [Write], [Seek], and associated traits.

Errors mostly originate from the underlying OS, but custom instances of Error can be created with crafted error messages and a particular value of ErrorKind.

Methods

impl Error[src]

pub fn new<E>(kind: ErrorKind, error: E) -> Error where
    E: Into<Box<dyn Error + Send + Sync>>, 
[src]

Creates a new I/O error from a known kind of error as well as an arbitrary error payload.

This function is used to generically create I/O errors which do not originate from the OS itself. The error argument is an arbitrary payload which will be contained in this Error.

pub fn last_os_error() -> Error[src]

Returns an error representing the last OS error which occurred.

This function reads the value of errno for the target platform (e.g. GetLastError on Windows) and will return a corresponding instance of Error for the error code.

pub fn from_raw_os_error(code: i32) -> Error[src]

Creates a new instance of an Error from a particular OS error code.

pub fn raw_os_error(&self) -> Option<i32>[src]

Returns the OS error that this error represents (if any).

If this Error was constructed via last_os_error or from_raw_os_error, then this function will return Some, otherwise it will return None.

pub fn from_sgx_error(status: sgx_status_t) -> Error[src]

Creates a new instance of an Error from a particular SGX error status.

pub fn raw_sgx_error(&self) -> Option<sgx_status_t>[src]

Returns the SGX error that this error represents (if any).

If this Error was constructed via from_sgx_error or then this function will return Some, otherwise it will return None.

pub fn get_ref(&self) -> Option<&(dyn Error + Send + Sync + 'static)>[src]

Returns a reference to the inner error wrapped by this error (if any).

If this Error was constructed via new then this function will return Some, otherwise it will return None.

pub fn get_mut(&mut self) -> Option<&mut (dyn Error + Send + Sync + 'static)>[src]

Returns a mutable reference to the inner error wrapped by this error (if any).

If this Error was constructed via new then this function will return Some, otherwise it will return None.

pub fn into_inner(self) -> Option<Box<dyn Error + Send + Sync>>[src]

Consumes the Error, returning its inner error (if any).

If this Error was constructed via new then this function will return Some, otherwise it will return None.

pub fn kind(&self) -> ErrorKind[src]

Returns the corresponding ErrorKind for this error.

Trait Implementations

impl Debug for Error[src]

impl Display for Error[src]

impl Error for Error[src]

impl From<ErrorKind> for Error[src]

Intended for use for errors not exposed to the user, where allocating onto the heap (for normal construction via Error::new) is too costly.

fn from(kind: ErrorKind) -> Error[src]

Converts an ErrorKind into an Error.

impl From<NulError> for Error[src]

fn from(_: NulError) -> Error[src]

Converts a NulError into a io::Error.

impl From<sgx_status_t> for Error[src]
